9 Claims. (Cl. 251-51) This invention relates to spouts for bath tubshaving as an integral part thereof diverter valves, by operation ofwhich water may be diverted to a shower head.

Combination spouts of this type as now manufactured have certainrecognized faults. For example, they have a tendency to leak where thediverter valve stem passes through the spout body due to the fact thatthe diverter valve stem is directly in the path of flow of water throughthe spout. This condition also causes the spout to be noisy in operationdue to vibration of the stem and valve and interferes with the flow ofwater through the spout causing a loss in pressure through the fixture.

It is the purpose of our invention to provide a combined spout anddiverter valve which is economical to manufacture, pleasing inappearance and overcomes the foregoing deficiencies of present dayspouts.

' Other novel features and their consequent advantages will beunderstood by those skilled in the art from a consideration of thefollowing description given in connection with the drawings in which:

Fig. 1 is a vertical longitudinal section taken through the combinationspout and diverter valve constructed in accordance with this invention.

Fig. 2 is a plan view of the combination spout and diverter valve andassociated control valves illustrating a typical installation,

Fig. 3 is a vertical transverse section taken on line 3-3 of Fig. 1,

Fig. 4 is a section similar to Fig. 3 but of a slightly modified form ofthis invention,

Fig. 5 is a section similar to Fig. 3 but of a still further modifiedform of this invention,

Fig. 6 is a vertical longitudinal section taken through a combinationspout and diverter valve adapted for an exposed shower connection, and

Fig. 7 is a vertical transverse section taken approximately on line 1-1of Fig. 6.

Referring more particularly to Figs. 1, 2 and 3 of the drawings, it willbe observed that the spout is formed in the usual shape having a nozzlel terminating in an enlarged portion or body 2 threaded to a flange 3which becomes part of the spout body and which in turn is threadedinternally to receive the supply pipe 4. The body of the spout isprovided with a partition 6 extending transversely across the body andhaving a valve port and seat I at approximately its center adapted to beclosed by a vertically disposed disc diverter valve 8'. A horizontallyextending counterweight or balance 9 is secured fluid through thefixture does not act as a dito the valve and extends through valve port1 into the nozzle portion I of the spout. The counterweight 9 isstreamlined so as to afford a minimum resistance to the flow of waterthrough the spout. IS

A valve stem I0 is attached to a lug ll extending laterally from'thecounterweight 9 and. extends through the spout body to provide a meansfor moving the valve and counterweight vertically from open to closedposition. -In open po- 10 sition the valve lies in-an enlargement formedin the spout body, and in closed position the valve 8 will seat andclose port I. The diverter valve is held in fluid tight relation againstthe seat by pressure of the incoming fluid through pipe 4, thecounterbalance insuring proper seating relation and equalization of thepressure against the disc. The valve stem It! extends upwardlythrough aguide web l3 and is guided in a bearing formed in a boss l4 upon theupper portion of the body of the spout. I A knob l5 may be attached tothe upper end of the stem to serve as an operating medium for the valve.

' It will be observed from the foregoing description that in openposition the counterbalance 9 is substantially below the normal flow of'fluid through the spout and that the valve stem I0 is to one side of theflow of fluid so that neither counterbalance nor stem are in the path offlow of fluid through the spout. By this arrangement the valve stem doesnot offer resistance to the flow of fluid and accordingly does not causea pressure drop and loss through the fixture. Furthermore, not beingsubject to the main flow oi fluid through the fixture it is not causedto vibrate and accordingly the fixture is much quieter in operation.Another important feature is the fact that the stem being out of themain flow of verter or baiile and direct the water toward its upper endand cause leakage where the stem passes through the spout body. Leak atthis point is substantially eliminated.

Reierring particularly to Fig. 2 there is illustrated a typicalinstallation in which the spout l is supplied through pipe 4 which isconnected to a cross l6 of special construction as disclosed in thepatent granted to M. J. Glauber, No. 1,653,956, issued December 27,1927, the latter being supplied through hot and cold water pipes l1 andI8, respectively, the hot and cold water being controlled by valves l9and 2 I. The shower (not shown) is-supplied through the side outlet 22of the cross Hi. It will be apparent that when valve 8 is raised toclosed position fluid not 55 being permitted to pass through the spoutwill discharge through outlet 22 and to the overhead shower (not shown).

In Fig. 4 is shown a slightly modified form of the invention in whichthe valve stem extends through the bottom of the spout and is actuatedby a yoke extending around the spout and terminating in a knob at thetop thereof. The construction employs a valve stem 24 which extendsthrough the bottom of the spout 26, the stem being threaded directlyinto the counterbalance 21 rather than to a lateral lug as in theprevious forms. That portion of the counterbalance 21 which contacts thewall of the spout surrounding the aperture through which the stemprojects is machine finished to provide a seating surface whereby thecounterbalance prevents undue leakage around the stem when the valve isin open position. A saddle 28 is secured to the lower end of the stemand extends outwardly from each side thereof. A U-shaped yoke 29 issecured to the saddle and extends upwardly and over the spoutterminating in a knob 3| at the top by means of which the yoke, saddle,stem and valve may be raised selectively into open and closed positions.

Referring to Fig. 5, it will be observed that a somewhat similararrangement is provided in which the valve stem and counterbalance arebelow the normal flow of fluid through the spout when the valve is inopen position. In this instance, however, the stem 24 is provided on itslower end with a knob 32 by means of which the stem and valve may beselectively moved into open or closed position.

Referring 'to the form of this invention shown in Figs. 6 and 7 thismodification is adapted for use where an exposed shower connection is tobe used. The spout l is the same as that described in Figs. 1 to 3 withthe exception that the body portion 2a is enlarged or elongated topermit the inclusion of a boss 33 which provides for a shower outletupon the exposed portion of the spout, that is, exterior of flange 3.The boss is bored interiorly to receive the end of a shower connectionand threaded externally to receive a packing nut 34. In this form of theinvention when diverter valve 8 is closed the water will pass up throughthe shower connection, that is, through boss 33 and the shower pipeinstead of through the outlet 22.

It will be obvious that the illustrated forms of this invention aremerely typical and practical embodiments thereof, and that changes maybe made in details of the constructions shown without departing from thespirit and scope of this invention as defined in the appended claims.
